Benefits of technology
[0014]A contiguous digital media storage system and method is disclosed herein. Generally, the system and method provide substantial increases in data throughput by storing data contiguously on a mass storage device. In one embodiment, the storage system comprises an allocator subsystem and a metadata subsystem on one or more memory devices. The allocator subsystem may be configured to identify sequentially sensitive data having a position within a sequence, and allocate one or more
Problems solved by technology
Data storage devices are still subject to some physical limitations, however, because devices such as hard drives still have moving parts.
The storage of digital media requires vast amounts of data storage capacity.
Compression reduces the storage requirements, and consequently the data rate requirements for digital media.
However, compression also adversely affects the quality of the digital media by introducing image artifacts or reducing detail.
If the throughput is insufficient then digital media frames can be dropped or skipped to the detriment of the overall quality of the digital media itself.
It is known that reading fragmented or randomized data reduces disk throughput.
Defragmentation is a complex and time consuming task especially given the file sizes and vast amounts of data

Embodiment Construction
[0035]In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention.
[0036]Central to the problem of storing digital media is the notion that traditional technologies, such as Storage Area Networks (SAN) or Network Attached Storage (NAS) do nothing to prevent or hold off randomization of data, other than to run optimization or defragmentation routines which have been the state-of-the-art for the past few years. At least some or all of the following trade-offs for optimization exist: no access to data during the optimization process; optimizing may take hours or days; newly recorded material may need optimizing before use; rendered or concurrently recorded material w...

A contiguous digital media storage system and method is disclosed. In one embodiment, the contiguous digital media storage system comprises a storage server, mass storage device, allocator subsystem, and metadata subsystem. Other embodiments may include additional storage servers or mass storage devices as well as one or more client devices. The system and method may be used with third party file systems. Generally, sequentially sensitive information is identified and stored contiguously based on its position within a sequence which substantially increases throughput. This position may be determined from information provided by client devices, file characteristics, or other ways. The system and method may store uniform and variable sized files contiguously.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to data storage and in particular to a system and method for recording and storing sequentially sensitive digital data such as digital media data so that it is physically contiguous and available for optimal retrieval speeds.[0003]2. Related Art[0004]Data storage technology has continued to improve throughout what has become known as the digital age. As a result, data storage devices have grown cheaper and faster with the passage of time. Data storage devices are still subject to some physical limitations, however, because devices such as hard drives still have moving parts. Currently, one of the most popular uses of the improvement in storage capacity and performance is the recording, editing and play back of digital media, including, but not limited to film, video, images, television, audio, and streaming media.[0005]As media production has moved from film, video tape and audio tape to digital te...
